Municipal energy renovation project saves 20 tonnes of CO2

The City of Aarhus has completed a project concerning energy renovation of a municipal administration building corresponding to the Danish building regulations’ low energy class 1. From a climate perspective, it is a far-reaching construction and the building will only be using a very low amount of energy.

An extra floor has been added to the building and the facade has been provided with glass covers that will help cool down and heat up the building – depending on the season. As to insulation features, between 400 and 600 mm of insulation material has been integrated in the exterior walls. Last but not least 90 square meters of solar cells have been installed – the major part on the roof and a minor part on the southern side of the building. The production of electricity from the solar cells is planned to be almost 6000 kWh pr. year.

All in all, the project entails that the City of Aarhus each year will be saving 85,000 kWh and 20.3 tonnes of CO². This is the equivalent of the yearly consumption of six single-family houses.

The building has been officially inaugurated on 15 June, 2010.
